Application ledvJunie 1, 1914. Serial No. 842,059.

To all whom t may concern.' f y Be it known that I, WILLIAM H. WAGNER, acitizen of the UnitedStates, residing at Burlington, in the county ofRacine and State of Wisconsin, have invented certain new and usefulImprovements in Needling- Machines, of which the following isaspeciication, reference belng had to the accompanying drawing, formlnga part thereof.

his invention relates to needling inachines and the objects of theinvention arel to lmprove needling machines in the manner to behereinafter described and claimed.

Referring to the drawings which accompany this s eciiication and form apart hereof, on wliich drawings the same reference characters are usedto designate. the same parts wherever #they may appear in each of theseveral views, and which drawings illustrate an embodiment of thisinvention, Figure l is an elevation of one side of the machine; Fig. 2is an elevation of the other side of the machine, parts being brokenaway and parts being shown in section; and ig. 3 is an elevation of thefeeding end of the machine, parts being broken away.

Referring to the drawings, the reference numeral 1 designates the frameof the machine on which the mechanism is assembled. The frame is tedneedle be s 2 and 3 which are positioned between guides formed on theframe. Each needle bed is supported by screwthreaded rods, preferably bya rod at each end, 4

which in turn are supported by the worm Wheels 5 which are screwthreadedto engage therods. Worm shafts 6 and 7 are provided for the worm wheelsand screwthreaded rods of each needle bed so that by rotating the saidshafts the needle beds can be raised or lowered to suit the thiclmess ofthe material -to be operated upon. To permit 'the machine to be run athigh speed the needle beams 8 and 9 are built up from steel in the formof rectangular tubes and are counterbalanced by springs 10, 11, l2 and13. They are also strengthened The needle beams are movable bothvertically and longitudinally within guides formed on the frame. I haveillustrated the machine as provided with two needle beds and two needlebeams and I prefer that the two sets of needles carried by the needlebeams shall not enter the material at the same time as by such anarrangement I can better counterbalance the machine and serovided withadjustable, slot-.

tion wheel 41 which 28 and is movable n shaft 40 toward or v and theratchet by trusses 14 and 15.l

cure more complete uniformityof feed of the material. Two drive shafts16 and 17 are located at opposite sides of the machine. Drive shaft 16is provided .with the fast pulley 18, loose pulley 19, chain wheel 20,and hand Wheel 21. Drive shaft 17 is provided with chain wheel 22 and isdriven froml shaft 16 by chain 23 which runs over the tightener 24 andis inclosed in the casing 25. Drive shaft 17 is also provided with ahand wheel 26 and is illustrated as provided with a pulley 27 for its-iiy wheel effect and with the friction disk 28. Drive shaft 16 isprovided with the counterbalanced eccentrics 29 and 30 which are lacedninety degrees apart and drive sha 17 is provided with thecounterbalanced 'eccentrics 31 and 32 which are also placed ninetydegrees apart and the eccentrics on the two shafts are so placed thateach needle beam is parallel with the needle bed with which it operates.The eccentrios are connected with the needle beams by the eccentric rods33, 34, 35 and 36. The hand wheels 21 and 26 are for turning the machineby hand when desirable or necessary as, for example, to lift a set ofneedles out of the material being operated upon. Levers 37 and 38 onopposite sides of the machine are connected with the belt shifter l39for starting and stopping the machine.

The shaft 40 is driven from shaft 17 by a speedchanging device which, asillustrated, comprises the friction disk 28 and the friccontacts withthe disk away from the center of disk 28 in the ordinary manner, theshipping bar 42 being held in any desired position of adiustment by thescrew clamp. 43. Shaft 40 is provided with the'miterwheel 44 whichmeshes with the miter' wheel 45`on shaft 46 which is also provided withAthe worm 47 which meshes with the worm wheel 48 on shaft 49. Worm Wheel48 is loose on shaft 49 but is adapted to revolve the shaft by means ofthe pawl wheel 51. A sprocket wheel 52 on shaft 49 drives the drawinroller 53 by means of the chain 54 and the sprocket Wheel 55. Shaft 49carries, at the opposite side of the machine, a. bevel gear 56 and asprocket wheel 57. Sprocket wheel 57 drives sprocket wheel 58 by thechain 59. Sprocket wheel 60 and sprocket wheel 58 are united and carriedby the stud 6l and sprocket wheel 60 drives sprocket wheel 62 andconveyer roller 63 by chain 64 which runs over the supporting conveyer66 is supported by rollers 63 and 67 and is. the feeding member for thefelt which is wound into a roll 68 on a spindle 69 in the ordinarymanner. The bevel gear 56 meshes with and drives a bevel gear 70 securedto shaft 71 and this shaft is supplied with two eccentrics 72 and 73which rock the bell cranks 74 and 75 by means of the connecting rods 76and 77. The bell cranks 74 and 75 are pivoted to the frame 1 and theirdownwardly extending ends terminate in knuckles 78 which engage withslides 79 retained within guides in the needle beams. On the oppositeside of the machine two links 8O and 81 are pivoted to the frame 1 inline with the pivots of the bell cranks 74 and 75 and their Alower endsterminate in knuckles which engage with slides retained within' guidesin the needle beams in the same manner as the downwardly extending endsof the bell cranks. This construction permits the needle bea-ms to bereciprocated up and down by the eccentric rods 33, 84, 35 and 36 and tobe moved longitudinally by the eccentrics' 72 and 7 8.

A weight roller 82 grips the material to the drawing roller 53.

The needles 83 are the ordinary barbed needles used with machines ofthis general character and are assembled on strips of Wood 84 or othersuitable material and are removably clamped under the needle bea-ms byclamps 85 which are provided with elongated slots 86 through whichprojects a bolt 87 provided with a nut 88 and a spring 89 between thenut and the clamp. By loosening the nut the clamp may be from the needlebeam so that its inturned lower end will clear the strip of wood towhich the needles are secured and then it may be pushed up out of theway with its lower end against the side of the spring will hold it inthis position.'

The function of the machine is to needle fabrics as, for example, tounite a loosely felted material to a stay of woven material such asburlap, for example. The burlap is designated by the reference numeral90, the felted material by the reference numeral 68, and the fabricproduced by needling them together is designated by the reference numeral 91. The burlap is led between rollers 92 and 93,' over roller 94and over needle idler 65. The slat swung awayl the needle beam and bed2. The felted material is led over needle bed 2 on top of the burlap andthe fabric is then led under roller 95, over needle bed 3, under roller96, over roller 97 and under roller 98 to the drawing roller 53 which ispositively driven by the chain 54 and the drivingr mechanism The feed iscontinuous but when the needles are in the fabric it is, of course,stopped but the stretch of the fabric permits the continuous feedwith-the intermittent stopping of the fabric by the needles. rl`hechange speed mechanism permits the feed to be changed to suit differentfabrics. The mechanism for longitudinally reciprocating the needle beamspermits of the machine being run at high speed without skipping andwithout danger of accidents.

In needling the average cloth, or material, the needle beams 8 and 9make about twenty vertical reciprocations to one horizontalreciprocation but this proportion is change able. Each of the needlebeams 8 and 9 makes a complete vertical reciprocation .for everyrevolution of the shafts 16 and 17. Each of the needle beams 8 and 9makes a complete horizontal reciprocation for every revolution of theshaft 71. The shaft 71 is driven from shaft 17 by the friction disk 28,friction wheel 41, shaft 40, Initer wheels 44 and 45, shaft 46, worm 47,worm wheel 48, shaft 49, and bevel gears 56 and 70, which constitutespeed reducing mechanism. The actual differences between the speeds ofrotation of the shafts 17 and 71 can be varied by shifting the frictionwheel 41 either to ward or away from the center of the fric tion disk28.

What is claimed is:

In a needling machine, the combination with two needle beams ofcounterbalancing springs supporting the needle beams, and shaftsprovided with eccentric mechanism for reciprocating the needle beams,the eccentric mechanism for one needle beam being set ninety degrees inadvance of the eccentric mechanism for the. other needle beam.

In witness whereof I hereto affix my signature in presence of twowitnesses.
